[tw] Getting a field value from a transcluded field name

[Steven Schneider]

Hi folks,

I've written a macro that identifies and presents tiddlers as slides in a 
slideshow with this: 

<>

My macro sets variable slidetag as follows:
<$set name=slidetag value="""$slidetag$""">


Tiddlers to be included in the slideshow are tagged with the name of the 
show (example: "welcome-to-class") and have a field of the same name 
(example: welcome-to-class) with value = 1 (or 2, etc.)

I want to dynamically set the bgcolor of the tiddlers based on slidenumber.

How do I reference a field that is defined through transclusion? In the 
code below, I'm trying to get the value of the field <> into a 
variable <>

<$list filter="[tag!nsort]" >
<$set name="slidenumber" filter="[all[current]field]">
...
doesn't work.

Suggestions?

Thanks, //steve.

Try

<$list filter="[tag!nsort]">
<$set name="slidenumber" tiddler=<> field="slidetag">
...

The trick is a new feature of the set widget (since 5.1.14) that allows a 
variable to be set directly from a tiddler field (or index).

Best wishes

Jeremy.

Thanks, Jeremy.

But, did you mean:

<$list filter="[tag!nsort]">
<$set name="slidenumber" tiddler=<> field=<>>

(It is almost working; i've got something else wrong now :)
